Suppressing and enhancing band gaps with glide-symmetric surfaces

Abstract [en]

We show how ultra-large-band operation can be obtained for both wave propagating (lenses, filters) and attenuating (bandgap materials) along metasurfaces. This is achieved by realizing the metasurfaces with glide-symmetric unit cells, invariant with respect to a translation and a mirror reflection. This requires two metasurfaces made with the same periodic lattice, off-shifted of a half a period along the directions of periodicity. This symmetry condition leads to the suppression of the closed stop-band at the X point of the Brillouin diagram, while it can maximize the width of the stopband at the Γ point. On one hand, the waves propagating between the surfaces can thus see a constant equivalent refractive index over a ultra wideband, which is useful to realize planar artificial lenses. On the other hand, the wide stopband can be employed for wideband bandgap providing strong attenuation, useful to block and guide waves in integrated circuits. The geometries under analysis will be described, and simulated and measurement results will be shown to validate the study.
